                },
            });
            calendar.render();
        });

Your problem is that you are using FullCalendar v4, not v5

Change your original code to from slotMinTime to minTime and slotMaxTime to maxTime and it'll work!

Continue using your v4 files, and use

slotMinTime: "07:00",
slotMaxTime: "18:00",

or, upgrade your JS File references to v5, and use

slotMinTime: "07:00",
slotMaxTime: "18:00",
